WILLIAM M. MITCHELL, OF LOUISVILLE, KENTUCKY.

RAIL-ANCHOR.

Application filed December 22, 1919.

To all whom it may concern Be it known that 1, WILLIAM M. MITCH- ELL, a citizen of the United States, and a resident of Louisville, in the countyof J efferson and State of Kentucky, have invented certain new and useful Improvements in Rail-Anchors, of which I do declare the following to be a full, clear, and exact description, reference being had to the accompanying drawing, forming a part of this specification.

The present invention, while adapted, so far as certain of its features are concerned, to rail anchors of other types, is more specifically directed to the improvement of that class of rail anchors that are adapted to be welded on to the rail. The invention consists in the features of novelty hereinafter described, illustrated in the accompanying drawing and particularly pointed out in the claims at the end of this specification.

Figure 1 is a view showing a vertical transverse section of a railway rail having my improved anchor applied thereto, the anchor and a part of the railway tie being shown in elevation. Fig. 2 is a view in horizontal section on line 2--2 of Fig. 1.

Fig. 3 is a view in side elevation showing a portion of the rail and cross tie and showing a modified form of my anchor in side elevation. Fig. 4: is a view in vertical section on the line 4.l of Fig. 3. Fig. 5 is a view of the blank from which the rail anchor shown in Figs. 1 and 2 may be formed.

A designates the railway rail,'the base flanges a of which are shown as resting upon a cross tie B in theusual manner.

As shown, my improved anchor is formed of one piece of metal, the upper portion of the anchor comprising a jaw adapted to grip one of the base flanges of the rail and the lower portion of the anchor comprising an abutment adapted to bear against the cross tie in order to prevent the longitudinal creeping of the rail. The jaw of my improved anchor comprises an upper member 0 adapted to bear upon the top surface of the base flange a of the rail, and a lower member (2' adapted to bear upon the lower surface of the base flange of the rail. The anchor comprises, also, a depending bar '0 that extends downwardly from the inner edge of the lower member 0 of the jaw and a member 0 that extends inwardly from the member a and at right angles thereto. The upper edge of the member 0 which is Specification of Letters Patent.

Serial No. 346,679.

adapted to abut against the face of the cross tie B, is flush with the upper face of the jaw 0 and hence bears against the bottom of the rail A and forms in effect an extension of the jaw.

, The upper member a of the jaw is preferably extended inwardly to such point that when the jaw is in position for use, the in ner edge of the upper jaw member 0 can be welded, as at (Z, to the web a. of the rail A. This welding may be done by any of the well known methods of welding adapted for such purposes, as for example, by the oxyacetylene process, in which a portion of a steel rod is melted under the intense heat of the flame and is fused onto the edge of the jaw c and onto the surface of the web a of the rail. The edge of the jaw 0 may be welded to the web of the rail throughout I its length or simply at one or more points, as indicated in Fig. 2 of the drawings. The main purpose of the welding of the edge of the jaw to the web of the rail is to se curely hold the anchor in position, as the greater part of the strain thrown upon the anchor under the tendency of the rail to creep would be resisted by the gripping or shackle action of the jaw upon the upper and lower surfaces of the base flange a' of the rail. By extending the upper member a of the jaw so that it can be welded to the web of the rail, the'welding is thus effected at a point where the danger of weakening the rail is avoided.

I Preferably, my improved anchor is formed from a metalplate that is cut to form L-shaped blanks shown in Fig. 5 of the drawing. After the blanks have been thus cut, they will be subjected to the action of suitable dies to effect the folds upon the dotted lines 3, 4: and 7 the folding of the blank upon the lines 7 serving to form the jaw members 0 and c, the folding of the blank upon the line 3 serving to form the abutment member 0 and the folding of the blank upon the line 4 serving to form the downwardly depending member 0 By thus forming the anchor, an eXceed-' fore described, except that the upper member 0 of the anchor jaw is formed at its inner end with an extension 0 turned upwardly and adapted to bear against the web'a of the rail A. As shown, the upward extension 0 of the aw is formed with a hole there through to receive a body of metal (Z that will be welded to the web a of the rail. This body of metal (Z may be welded to the web a of the rail before the anchor is applied or the body of metal (Z may be fused to the web a through the hole formed in the upward flange 0 of the anchor. The upper edge of the anchor is shown as connected tov the web a of the rail A by being welded thereto as at (Z this welding being accomplished by any of the familiar welding methods adapted for the purpose and at as many points and to such extent as may be desired.

lVhen the upturned portion 0 (as shown in Figs. 3 and 4:) is provided with a hole to receive a stud or lug projecting from the web of the rail, the end of this stud or lug (Z may be upset after the anchor has been placed in position for use. In such case, it is not necessary that the upwardly extending member 0 of the anchor shall be welded to the rail.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is l. A one-piece rail anchor the upper portion of which comprises a jaw to engage the base flange of a rail and the lower portion of which comprises an abutment having angularly depending members, one of said members extending along and depending vertically from the inner edge of the lower part of the jaw, the other of said members being integral with the vertical edge of said vertically depending member and bent angularly thereto and having a free upper edge.

2. A one-piece rail anchor the upper portion whereof comprises a jaw to engage the base flange of a rail and the lower portion whereof comprises an abutment having angularly depending members, one of said members extending alongand depending from the inner edge of the lower part of the jaw and the other of said members extending inwardly at right angles to said first mentioned member.

3. A one-piece rail anchor the upper portion whereof comprises a jaw to engage the base flange of a rail and the lower portion whereof comprises an abutment having angularly depending members, one of said members extending along and depending from the inner edge of the lower part of the jaw and the other of said members extending inwardly at right angles to said first mentioned member and having its upper edge in line with the rail engaging surface of the lower member of the jaw.

4:. The combination with a railway rail and a cross tie, of a rail anchor the upper portion whereof comprises a jaw adapted to engage the base flange of the rail, the upper member of said jaw extending entirely across the base flange of the rail and being welded to the web of the rail.

5. The combination with a railway rail and a cross tie, of a rail anchor the upper portion whereof comprises a jaw adapted to engage the base flange of the rail, the upper member of said jaw extending entirely across the base flange of the rail and being formed at its inner end with an upturned portion united to a part welded to the web of the rail.

6. The combination of a railway rail having a welded on lug projecting from its web, a cross tie, and a rail anchor the upper portion whereof comprises a jaw adapted to engage the base flange of the rail, the upper member of said jaw extending entirely across the base flange of the rail and being formed at its inner end with an upturned portion having a hole to receive the lug projecting from the web of the rail.
